59. ADJUST FRONT CHAIN (figs. [36], [37], and [38]).
a. At the time front chain adjustment is made, inspect chain for correct lubrication and, if necessary, adjust front chain oiler (par. [61]).
b. Chains wear unevenly and some stretch may result, making tight and loose sections. For this reason, engine must be turned and chain rotated to position of least slack at the time adjustment is made.
c. A correctly adjusted front chain has ½–inch, or slightly more, free up‐and‐down movement midway between sprockets, at inspection hole. Chain must never be run taut (no slack at tightest point). Chain must never be allowed to run loose enough to cause jerky, noisy action and/or strike the chain guard.
d. Adjustment of front chain is made by shifting transmission on its mounting base. This will affect adjustment of gear shifter control linkage, clutch control linkage, and rear chain.
e. How to Adjust Front Chain.
(1) Remove inspection hole cover by removing screws and lifting cover from front outer chain guard, exposing chain ([fig. 36]).
(2) Obtain tightest chain position by rotating chain to position of least slack. Test amount of slack by lifting and depressing chain with finger. Use a free up‐and‐down motion of the finger to make this test.
